Adjustable colluvial stent

The present invention relates generally to the field of medical devices. In particular, the present invention relates to medical devices for facilitating flow of fluids and materials in and/or between adjacent body cavities, e.g., a stent that maintains an open flow path between body cavities. In one example, the stent may have a restricted configuration and an expanded configuration. In the expanded configuration, the stent may have first and second retention members and a saddle region extending therebetween. The saddle region may include a coil configured to apply a restoring force to a tissue surface juxtaposed with the first and second retention members, respectively. 本发明总体涉及医疗装置领域。特别地，本发明涉及用于促进流体和材料在相邻体腔中和/或之间流动的医疗装置，例如，一种在体腔之间保持开放的流动通路的支架。在一个示例中，支架可具有受限形态和扩张形态。在扩张形态中，支架可具有第一和第二保持构件和在其之间延伸的鞍状区域。鞍状区域可包括线圈，其配置为向分别与第一和第二保持构件并置的组织表面施加恢复力。
